How do you find pressure from temperature? Use the formula: k = T1/P1. For example, if a gas at an initial temperature of 300 K and an initial pressure of 100 Pa, drops by 50 Pa, the proportionality constant k = 3 K/Pa = 300/100 = T1/P1. Multiply the drop in pressure by the proportionality […]
Why is there a dielectric between the plates of a capacitor?
Why is there a dielectric between the plates of a capacitor? Dielectrics in capacitors serve three purposes: to keep the conducting plates from coming in contact, allowing for smaller plate separations and therefore higher capacitances; to increase the effective capacitance by reducing the electric field strength, which means you get the same charge at a […]
Can a fetus still grow if there is no heartbeat?
Can a fetus still grow if there is no heartbeat? This is called an anembryonic pregnancy, which is also known as a blighted ovum. Or it may be that your baby started to grow, but then stopped growing and they have no heartbeat. Occasionally it happens beyond the first few weeks, perhaps at eight weeks […]
Are any vitamins worth taking?
Are any vitamins worth taking? Science tells us that taking most vitamins is worthless—but a few buck the trend. In the last few years, a number of studies published in the Annals of Internal Medicine underscored a fact that scientists have become increasingly sure of: The vast majority of vitamins and mineral supplements are simply […]
Are the two triangles similar How do you know no yes by AA?
Why does copper have a high electrical conductivity?
Why does copper have a high electrical conductivity? Thus, copper is a lattice of positive copper ions with the movement of free electrons among them. Due to movement of electrons freely through the metal, they are also known as conduction electrons. The presence of these conduction electrons makes the copper a good conductor of electricity […]
Does heat depend on temperature?
Does heat depend on temperature? Heat is a type of energy, but temperature is not energy. Heat depends on mass of the substance, however; temperature does not depend on the quantity of matter. If you give heat to a matter, you increase its temperature or change its phase. Does rate of heat loss depend on […]
How can energy resources be classified?
How can energy resources be classified? Energy sources can be classified into two types: nonrenewable and renewable. Nonrenewable resources, such as fossil fuels and nuclear material, are removed from the earth and can be depleted. These resources have been the most used type of energy in the modern era. What are the three categories of […]
What is true color in water?
What is true color in water? While relatively small quantities of water appear to be colorless, pure water has a slight blue color that becomes a deeper green as the thickness of the observed sample increases. The blue hue of water is an intrinsic property and is caused by selective absorption and scattering of white […]
Can material exist in all the three states?
Can material exist in all the three states? 2 Answers. Every element can exist in the 3 basic states: gas, liquid, solid. It is just a matter of enough freezing and high pressure (to solidify gases, even Helium) or enough heat and low pressure (to vaporize metals, even tungsten). Does all fire have smoke? As […]
